The concentrations and isotopic ratios of CO_2, CH_4 and N_2O, as well as the O_2 concentration, were measured using ground-fixed stations, aircraft, ships and scientific balloons, and global pictures of their temporal and spatial variations were obtained. By analyzing the observed results using newly developed atmospheric transport models, the variations of the three gases were closely examined and their global cycles were quantitatively evaluated. The concentrations of atmospheric CO_2, CH_4 and N_2O over the last 700 kyrs were reconstructed by analyzing the Dome-Fuji deep ice core from Antarctica, and their variations were interpreted.

利用地面固定站、航空器、船舶和科学气球测量了CO_2、CH_4和N_2O的浓度和同位素比值以及O_2浓度，并获得了其时空变化的全球图像。通过分析新开发的大气传输模式的观测结果，仔细检查了这三种气体的变化，并定量评估了它们的全球循环。通过对南极冰穹-富士冰芯的分析，重建了近700 krs来大气CO_2、CH_4和N_2O的浓度，并对它们的变化进行了解释。
